A Ni-containing decaniobate incorporating organic ligands: synthesis, structure, and catalysis for allylic alcohol epoxidation

An organic–inorganic hybrid polyoxoniobate, Na 8 {Ni[Ni(en)] 2 Nb 10 O 32 }·28H 2 O ( 1 ) (en = ethanediamine), has been synthesized and characterized. It represents the first example of a trinuclear nickel-containing polyoxoniobate. The catalysis of 1 for allylic alcohol epoxidation was investigate...

Zusammenfassung:An organic–inorganic hybrid polyoxoniobate, Na 8 {Ni[Ni(en)] 2 Nb 10 O 32 }·28H 2 O ( 1 ) (en = ethanediamine), has been synthesized and characterized. It represents the first example of a trinuclear nickel-containing polyoxoniobate. The catalysis of 1 for allylic alcohol epoxidation was investigated at room temperature in aqueous solution, and was found to catalyze the epoxidation of 3-methyl-2-buten-1-ol with high conversion (98%) and selectivity (94%). Furthermore, magnetic measurements showed that the compound exhibits ferromagnetic interactions.
